TECHNICAL FIELD
[0001] The utility model relates to unloading machine dust removal technical field, concretely is a bridge type grab ship unloader dust removal device. BACKGROUND
[0002] The bridge type grab ship unloader is a bridge type crane using a moving trolley to drive a grab to grab materials from a ship cabin and unload the materials to a funnel on the machine, and belongs to intermittent (or periodic) ship unloading machinery. It is mainly used to transport solid bulk cargo from the ship cabin to the bulk conveyor belt on the wharf, and is a commonly used equipment in ports, shipyards and water construction sites. Dust is generated when the ship unloader is unloading, and the dust is generated when the grab is opened and the materials fall into the unloading hopper. A large instantaneous airflow is generated in the unloading hopper. The unloading operation area is usually near the sea or river, and is greatly affected by the wind. The dust spreads with the wind and causes dust pollution in a large area around the ship unloader.
[0003] According to the bridge type grab ship unloader dust removal device (authorized publication number: CN213802041U) disclosed by the patent network, the bridge type grab ship unloader dust removal device includes a grab, a dust removal hopper, a material guide cylinder, etc. to realize dust removal work.
[0004] According to the above description, the applicant believes that the following problems exist:
[0005] The bridge type grab ship unloader dust removal device uses a grab, a dust removal hopper and a material guide cylinder to realize dust removal work. This device performs filtering work through a U-shaped filter screen alone during use. The filtering and dust removal effect is poor. The U-shaped filter screen is fixed in the filter chamber. Although it can be cleaned by the cleaning ring, dust will still adhere to the periphery of the U-shaped filter screen after a long time of use. The cleaning effect is poor. The U-shaped filter screen cannot be removed for thorough cleaning, which affects the dust removal effect. Therefore, the device needs to be improved. UTILITY MODEL CONTENTS

[0015] Compared with the prior art, this utility model provides a dust removal device for a bridge-type grab unloader, which has the following beneficial effects:
[0016] 1. The dust removal device of this bridge-type grab unloader utilizes a dust removal mechanism. When the unloader body is in use, a large amount of dust is generated in the air as it conveys materials into the hopper. Under the action of the first and second fans, the dust generated during material feeding is conveyed to the filter box through the conveying pipe. The filter plate assembly provides initial filtration of the air. After initial filtration, the air enters the filter box and undergoes secondary filtration under the action of the first filter plate. There are three first filter plates, which perform multiple filtrations to improve the filtration effect. The filtered air is discharged through the exhaust pipe, improving filtration efficiency and dust removal. Furthermore, the threaded rod and connecting frame can move the sealing cover, mounting frame, and first filter plate. The sealing cover not only seals the top of the filter box but also facilitates cleaning of the first filter plate and the inside of the filter box after long-term use. This improves the filtration effect while ensuring the quality of dust removal. The device is also easy to operate, eliminating the need for manual opening of the sealing cover.
[0017] 2. The dust removal device of this bridge-type grab unloader, through the setting of a limiting mechanism, allows the unloader to unload materials during use. When the dust generated is transported by the first and second fans and initially filtered by the filter plate group, the filter plate group can be limited by the action of the insertion rod, the moving plate, the pull ring and the spring, so that the filter plate group is in a stable state inside the conveying pipe. At the same time, it can facilitate the subsequent removal of the filter plate group for cleaning or replacement, improving the convenience of operation and the filtration effect.
